Unless someone puts a thermocouple in there and measures the temperature, it's all conjecture. My theory is that the metal bucket will transfer some heat and the holes should be enough to prevent the fan from building pressure. Other than that, I'm willing to wait and see what happens.

FYI an HID lamp puts out more light and less heat. An incondecent bulb puts out light as a byproduct of heat. An HID lamp produces light via an arc stream, that produces UV light which is converted to “white” light based on the elliments introduced to the arc stream. Therefore high light output low wattage. Additionally extremely long life of the bulb.

love the hids on our GTI but the leds on the Passat seem to have better cut off and a more concentrated beam.
Of course, there is 10 years of difference in techology and two different cars so not a direct comparison.

The hids require a ballast so another thing to be mounted.

Lots to consider.

Thanks

A word of caution, replacing the left/right blinker indicators was a mistake... LEDs are too bright and my entire cabin flashes green at night when i set the indicator!
I made the same mistake and know exactly what you're talking about. There were also 1 bulb (above the speedometer I think) that I couldn't get a LED bulb to fit. How did you manage to change them all out?

Haha, I am glad I'm not the only one. The first set of bulbs I used were indeed to big to to fit most of the holes actually... I ended up finding these that fit every socket.

They are incredibly small but still plenty bright.

CT06033.., when you went leds. Did you have to change the voltage regulator?? Or was it just plug in? And I’m have the original wiring with the U20 engine. No swap for me yet.., can I still run the leds with the vintage wiring setup?? Shamus.

I just swapped mine out, but I cannot not use the dimmer since I didn't update the electrical.
